Why We Walk: On behalf of the more than 5 million American's living with Alzheimer's disease, thank you for rallying around a cause that affects 1 in 3 people in the communities where you work and live. As a Walk to End Alzheimer's® National Team, Legrand | AV will be forming teams across the country. The awareness and funds raised will advance the care, support and research efforts of the Alzheimer’s Association.
